HYDRAULIC Mo ToR.

SPECIFICATION forming part of Letters Patent No. 424,223, dated March 25, 1890. Application filed May 12, 1887. Renewed September 20, 1889. Serial No. 324,481. (No model.)

To all whom it may concern.-

Be it known that I, HENRY RoEsKE, a citizen of the United States, residing in the city and county of Philadelphia,State of Pennsyl- .vania, have invented a new and useful Inn 'provement in Hydraulic Motors, which improvement is fully set forth in the following specification and accompanying drawings.

My invention consists of a hydraulic motor adapted for operating the pistons of a pump, the cocks of. a filter, and other devices, as will be hereinafter fully set forth.

Figures 1 and 2 represent partial side elevations and partial vertical sections of a hydraulic motor embodying my invention.

Similar letters of reference indicate correspondingparts in the two figures. V Referring to the drawings, A represents a tank, which is mounted centrally ona standard B, whereby it may turn on the standard The said standard has arms B, furnishing rests for the tank when tilted Rising from the center of the tank is a plate C, which thus divides the tank into two compartments. The bottom D of one of the compartments is raised for a port-ion of its length, formingthe peak E and leaving a depression F in the tank at the outer end of said. bottom D. Each compartment of the tank is provided with a discharge'cockG, and located over the center of the tank is a supply-cock H.

J represents two levers, which are mounted on standards K and cross each other, the upper ends of the levers being freely fitted between rollers L, which are connected with the under side of the tank A. The lower ends of the levers are freely connected with cocks M of a pipe N. V

lVitl1in the compartment opposite to that containing the peak E is placed a ball or weight P, which is adapted to roll or move to opposite ends of said compartment, the tank, however, being in equilibrium when the ball is removed and the other compartment free of water.

The operation is as follows, the parts being in position shownin Fig. 1: Water is directed into the tank, and, owing to the oblique direction of the tank, the water in the present case fills the right-hand compartment. As soon as the water overflows the peak E it fills the depression F, and thus weights the outer end of the compartment and overcomes the weight of the ball P, whereby the tank turns 011 its fulcrum and the parts assume the position shown in Fig. 2, the ball I? rolling to the center of the tank. The right-hand com= partment of the tank is gradually cleared of its contents by means of its cock G, and wa ter from the cock H meanwhile fills the lefthand compartment. WVhen the latter conn partment is sufficiently supplied, the right hand compartment is empty and the left end of the tank descends, the ball P rolling toward said end and assisting said descent. right-hand compartment now receives a supply of water and the subsequent operations are similar to those hereinbefore stated. By these means the levers J are alternately raised and lowered and the cooks M opened and closed, the pipe N in the present case being employed in connection with a filter, where by, owing to the cooks M, fluid to be filtered is caused to enter said pipe N in reversed directions.

In lieu of the cooks M, pistons of pumps or other devices to be operated may be con nected with the levers J.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- I 1. A hydraulic motor composed of a stand ard, a tank having two compartments and pivotally resting on said standard, each of said compartments having discharge-cocks, a supply-cock common to both compartments, a lever operated by the oscillation of said tank, and a pipe with cock therein, the latter controlled by the said lever, substantially as described. I

2. In a hydraulic motor, a pivoted tank having two compartments, one of which has the peak E and the other provided with the loose ball P, and each of said compartments having a discharge cock, in combination with a supply cock common to both compartments, substantially as and for the purpose set forth.

3. The standard 13, in combination with the The two-compartment tank A, pivotally resting on said standard, one of the said compartments having the peak E and the other provided with the loose ball P, and each having a discharge-cock, a common supply-cock for said compartments, the levers J, each having one of its ends freely operating between the rollers L L of the tank, and the pipe N,With cock M therein, the said cock M being controlled by the said lever J, substantially as described.

4:. An oscillating two -co1npart1nent tank having the rollers L L, in combination with the lovers J J having their upper ends connected with opposite ends of the tank, and

the pipe N, with cocks M M, each of said cocks I5 HENRY ROESKE. Witnesses:
